Abstract

The present disclosure relates to a nanofiltration membrane and a method of manufacturing a nanofiltration membrane. The method includes providing a support structure having a first mesoporous layer made of TiOand/or ZrOand a second porous layer adjacent to the mesoporous layer made of aluminum oxide. The method further includes grafting an anchoring group within pores of the first mesoporous layer, wherein the second layer is inert to the grafting step. An initiator for a surface-initiated atom transfer radical polymerization (SI-ATRP) reaction is covalently bonded to the anchoring group. The support structure is impregnated with a monomer and a solvent, and a polymerization reaction is performed, which includes passing a catalyst through the mesoporous layer, the monomer being configured to start the polymerization reaction by grafting from the initiator in the presence of the catalyst.
